Why isn't transform.position.Set working?

I am not new to programming or even video game development, but I am very new to Unity, and this one currently has me stumped.

I am following the Space Shooter guide, and currently have a single GameObject in my PlayerController class

Code (CSharp):

1. public GameObject blastObjTemplate;
2.     private GameObject blastObj;
3.  
4.     void Awake()
5.     {
6.         blastObj = Instantiate(blastObjTemplate, transform.position, transform.rotation) as GameObject;
7.         blastObj.SetActive(false);
8.     }

I then want to have that object appear at the same point as the player after hitting the attack button, so I do this:

Code (CSharp):

1.         blastObj.SetActive(true);
2.         blastObj.transform.position.Set(transform.position.x, transform.position.y, transform.position.z);

But blastObj remains at origin. After debugging the code, I can see that the values for transform.position are as expected, but blastObj.transform.position remains the same after Set. What gives?

 

Some one wrote a workaround here: http://answers.unity3d.com/questions/225729/gameobject-positionset-not-working.html

Maybe this will help?

 

Okay, that worked. Thanks! Didn't realize that transform.position returned a copy.
